3.Recall from Lab 1 that a histogram of the current salary data indicated a strongly skewed to the right distribution. Let’s examine a QQ plotto see that it supports this non-normal feature. Create a Q-Q plot for the salary data. Q-Q plots are created via Analyze> Descriptive Statistics> Q-Q plotsProvide a sketch and explain how the QQ plot supports that the underlying distribution of salary does not appear to be normal (or bell-shaped)..
4.You would like to compare the distribution of salary for minorities versus non-minorities. To obtain numerical summaries or any graph (except boxplots) for current salary by minority status, we need to split the data file. Use Data> Split Fileand choose Organize output by groups. The grouping variable is minority classification.Note:Doing this successfully does not produce any noticeable changes in the SPSS windows; there will only be a few short lines of output in the Output window confirming the split. Create histograms separately for minorities and non-minorities. Compare and contrast the distribution of salary for the two groups. Can we use the same description for both histograms?
5.Obtain descriptive statistics for current salary by minority status. Remember the data is still split, so just generate the descriptive statistics by selecting Analyze> Descriptive Statistics> Frequencies and then choose the summary measures you want under the Statisticsbutton. Fill in the basic summary measures for current salary by minority status.
6.To create side-by-side boxplots for current salary by minority status, the data file should NOTbe split. Go back to the Split File dialog box and choose Analyze all cases, do not create groups. Again, the only change will be one line of output confirming the data has been “un-split.” Next use Graphs> Legacy Dialogs> Boxplotwith Simple and Summaries for groups of cases. Minority Status is the variable for the category axis, and current salary is the variable. How does the distribution for current salary compare for minorities versus non-minorities (based on the histograms, descriptives, and side-by-side boxplots)?
